I’ll be the first one to say it, someone is going to complain about the reflection of the collectors. I would assume that things like this are taken into account but you can never tell in this litigious world.

Abengoa Solar Inc., a Spanish technology company that has several smaller solar-thermal projects in Spain, North Africa and the United States, will build and run the Solana Generating Station. Solana will use 2,700 "troughs" of mirrors lined up across former alfalfa farmland, focusing sunlight on tubes in the middle of the troughs. The tubes will be filled with a petroleum-based chemical that will heat up to 735 degrees, and transfer their heat to water, making steam and spinning turbines in two 140-megawatt generators. The petroleum liquid is reused in the tubes, not burned. The plant also will use molten salt to store heat and continue generating electricity for as long as six hours after the sun sets. That’s key in Arizona, where residents use the most electricity between 5 and 6 p.m., when the sun is low in the sky and common solar panels struggle to generate electricity.
